And likewise, this theme shows up in Tom DeMarco's classic book Slack, which contrasts "efficiency" (the rate at which an organization is moveing towards some goal) vs "effectiveness" (the ability of the organization to choose and steer towards better goals). An important theme of the book is that an organization running full-tilt (maximum "efficiency") intrinsically reduces/eliminates its needed human "slack" to reflect and iterate towards the correct goals. DeMarco also digs into into the many organizational and management anti-patterns, with supporting research, that harm both effectiveness and efficiency (and just plain human well being...)
